The news just keeps getting worse for Airbus. AvWeek noted some Boeing insiders were speculating that Airbus completely underestimated the difficulties involved in wiring the double-decker design, and that's coming back to haunt them with a vengeance.

But Boeing is wisely staying officially silent about these troubles (as far as I know). The 787 is, in its own way, perhaps even more radical than the A380, but we won't know if their design has any hidden "gotchas" until some time next year.
